United States Patent SHAVING IMPLEMENTS Jacob L. Kleinman, Arverne, N.Y. v Application July 29, 1953, Serial No. 371,065'

19 Claims. (Cl. Sli-40) 'I'his invention relates to the construction ofshaving implements in general and more particularly to a type known asan injector razor or magazine feeding razor, which is constructed in amanner wherein the blades are fed from the magazine directly into therazor head and held in position in a locked manner for shaving purposes.

My novel construction is capable of being utilized in connection withVarious types of shaving implements, but particularly so with a type ofan injector razor adapted to hold a blade having two individual oppositecutting edges.

In accordance with my invention, I produce a shaving implement includinga razor-head structure comprising an inner member having a top portionor platform adapted to form a seat for a razor blade having twoindividual cutting edges, and an outer member having a roof or plateportion adapted to hold the razor blade secured to such seat for shavingpurposes, and wherein the said head structure is provided with a wallhaving a zig-zagged or corrugatedly-shaped slot to receive a zig-zaggedor corrugated linger of a blade magazine to move or separate theplatform and the plate portion from each other to an extent whereby arazor blade having two opposite cutting edges may be positionedtherebetween without damaging such cutting edges.

To illustrate the ordinary commercial utility of my novel shavingimplement in daily life, a shaving implement constructed in accordancewith my invention, of whatever style or type it may be made, could beutlilized to great advantage. For illustrative and clarificationpurposes I desire to point out the following: Many attempts have beenmade to produce an injector razor wherein a double edged razor bladecould be inserted therein directly from the blade magazine, but none ofsuch attempts have met with any success. The reason for suchunsuccessful attempts are as follow: It should be borne in mind, thatfor the purpose of moving a double edged razor blade from the magazineinto the razor head, particularly so when such blade is to serve thepurpose of pushing the used blade out of the head structure, the razorhead must be so constructed that when the magazine finger is placedwithin the finger-slot of the head structure such linger must perform.the following functions.

First, the lugs engaging the cutting edges must be moved (horizontallyor cross-sectionally of the handle) farther apart from each other to anextent whereby neither one of the two opposed cutting edges of the bladecould touch such lugs while such blade is being moved into desiredposition for shaving purposes.

Second, the portions of the blade seat and of the roof section, of therazor head portion situated adjacent to the outlet slot of the magazine,must be separated from each other (longitudinally of the handle) only tosuch an extent whereby the blade may be permitted to enter the spacetherebetween; for example, if the thickness of the blade is .010 inchthen the space between the front portions of the blade seat and of theroof portion, when so separated from each other, should be about .012inch,

2,734,264 Patented Feb. 14, 1956 but the remaining portion of the spacebetween such blade seat and roof portion must be of a lesser degree; (asa matter of fact, the rear portions of such blade seat and roof portionshould, by means of spring tension, engage each other) so that when theincoming blade enters the space between the blade seat and the roofportion it will engage and eject, endwise, the used blade from itsposition within the razor head without distortion while such incomingblade is being held in frictional engagement within the remainingportion of the space between the blade seat and the roof portion. Andwhen the magazine finger is removed from the head structure then suchblade must be clamped evenly and rigidly between the portions of theblade seat and the roof portion, and also between the lugs engaging theend portions of the cutting edges, to an extent preventing lateralmovements of such blade when positioned upon its seat for shavingpurposes.

Third, the eXtreme rear end portions of such platform seat and roofportion must be tapered to an extent whereby when the finger moves thefront end portion upwardly from the platform seat the rear end portionswill rest upon a full surface and not upon edge portions so as not todistort the operation of the parts.

It can therefore be seen that an injector razor, to be practical anduseful in combination with a razor blade having two opposite cuttingedges, must be built to be able to perform the above-mentionedfunctions; none of the injector razors designed to hold a double-edgedrazor blade are able to perform such functions. It is for this reasonthat attempts, heretofore, to produce a practical and useful injectorrazor to be used in combination with a double-edged razor blade has beenunsuccessful.

Whereas an injector razor made in accordance with my invention, which isdesigned especially to perform the above-mentioned functions, is fullyapplicable for use in combination with a double-edged razor blade. Theblade seat is provided with two opposite comb-sections each to supportits adjacent cutting edge. The blade can easily be fed from the magazinelinto the razor head in a manner whereby the blade will be held underyieldable frictional engagement during its slidable movement, and beheld, firmly, in its seat for shaving purposes.

It may also be pointed out that the corrugated slot is of a shapetapered, gradually, downwardly to a narrower size than that of its uppersection, so that the magazine linger (which is of similar shapecross-sectionally), when inserted into the slot, will more readily moveor separate the upper portions of the head structure further apart fromeach other without strain upon the movable parts of such head structure.j

In addition to the above the following may be pointed out: The size inwidth of an average double-edged razor blade is about seven eighths ofan inch; the reason for such a size is that the average razor head, forholding a double-edged razor blade, is so built that it requires a razorblade of such a size in width. Whereas the structure of my invention isof such a type that the razor-head, in actual size, can be made to holda double-edged razor blade of only one quarter (1A) of an inch in width.

It must be remembered, that a razor blade is used several times and thendiscarded, so that the material comprising such a razor blade becomes acompletely useless Waste. Razor blades are made in the millionsannually. A comparison will clearly show that the amount of materialnecessary to manufacture two (2) millions of the ordinary double-edgedrazor blades for `use in connection with the present type ordinaryrazors would be suliicient to produce seven (7) millions double-edgedblades for use in combination with the razor head made in accordancewith my invention. Such a tremendous savingof razor blade material,annually, is of such great importance to razor blade manufacturer thatthis in itself would cause my invention, which would be instrumental inprocuring such tremendous annual saving of material, to be of greatcommercial value to the razor manufacturer.

There is, therefore, thus produced in accordance with my invention, aninjector razor comprising a head structure adapted for use incombination with a razor blade of considerable narrow width having twoindividual opposite cutting edges, wherein each side-comb-portion of thehead structure in combination with its respective cutting edge of thedouble-edged razor blade is adapted to shave without changing theposition of the blade upon its seat, and wherein the head structurepermits slidable movement of a double-edged razor blade upon its seatupon yieldable frictional engagement without injuring the cutting edges,and wherein the head structure is provided with a corrugated slot of ashape tapered downwardly to a narrower size than that of its uppersection, to receive a magazine linger of similar shape cross-sectionallyfor readily operating the upper portions of the head structure toreceive or eject a double-edged razor blade, thereby providing the userof an injector razor with a magazinefeeding shaving implement having twocutting edges for quick and satisfactory shaving purposes.

Thus, a shaving implement made in accordance with my invention,comprises a properly constructed razorhead, and a removable blademagazine, each built in a practical manner to cooperate with each other;such shaving implement comprising a practical long sought fordouble-edge magazine razor affording a maximum of shaving surface notobtained heretofore by an injector razor; and therefore provides fastand superb shaving performances, great satisfaction and comfort to theuser. It is believed that such a shaving-implement can be utilized togreat advantage and therefore prove quite valuable commercially.

The variety of possible application of my novel construction withdifferent types of razors, as herein above indicated, is so prolificthat for the purpose of illustrating the invention the specic embodimentof my invention in its application to a shaving-implement exhibiting thegreatest diculties has been selected. Such a shavingimplement is onewhich necessarily must conform most rigidly to the contours of theportion to be shaved and one which has the eld of greatest possiblecommercial use. For this purpose I have selected for illustration of mynovel construction, a shaving implement constituting a magazine feedingtype razor, so that the principles of construction may be bestillustrated in a razor known as a magazine razor or shaving implement.

The objects of the present invention are attained by a novelconstruction which will be hereinafter described and illustrated in thedrawing in connection with a specific embodiment of the invention.

Referring more particularly to the drawings, in which similar referencecharacters identify similar parts in the several views, in my novelshaving-implement.

Arrow A indicates a razor head structure, usually known as a razor. 10indicates the outer member and 11 indicates the inner member. The innermember 11 comprises a wall portion 12 and a platform 14. This platform14 is adapted to form a seat for a razor blade 1S. The wall portion 12is provided with a slot 16 so formed that when the platform 14 is bentupon its curvature 17 the blank 18, from the slot 16, is liftedsimultaneously upwardly in line with the platform 14 forming acontinuation thereof. The longitudinal front end portion of the blank 18and the opposite longitudinal end portion 19 are each curved downwardlyto form comb or guard sections 21. The platform portions adjacent thecomb sections 21 are each provided with the usual slots or openings 22.

The outer member 10 is provided with a wall section 24 having outwardlyextending end sections 25. These end sections 25 are shaped or bent intooutwardly lz-ulfred curved sections as at 26 forming inwardly disposedflange portions 27 and 27'. These flange portions 27 and 27 are carryingbetween them a blank element or cover element 28, for a purpose whichwill be hereinafter explained.

The wall section 24 is provided with inwardly disposed wall portions 29and 30. The wall portion 30 is provided with a zg-zagged or corrugatedlyshaped slot 31 which is of a shape tapered, gradually, downwardly to anarrower size as shown at arrow B than that of its upper sectionindicated by arrow C.

The end portions 12' of the wall 12 are shaped or bent inwardly in amanner, for example, as indicated by arrows D, and are positionedagainst the inner faces of the wall portions 29 and 30. This wallportion 12 is also provided with hook elements 32 and with an extension12".

The outer member 10 is provided with a handle 35 secured thereto byrivets or screw elements This handle 35 is provided with ascrew-threaded opening 37 and with a recess or groove 38.

My shaving implement may be assembled in the following manner; the hooks32 are placed, in a hingeable manner, within the openings 33 therebyconnecting the inner member and outer member to each other. The spring39 is then placed into proper position, having its extension 44 placedwithin the recess or groove 38. The screw element 40 is then placed,loosely, within an opening in the spring 39 (opening not shown) and thenin a rotatable manner into the screw-threaded opening 37 having theshoulder, of its knurled head 41, force the spring 39 towards the member11 to an extent whereby the bulged portion 42 presses the inner member11 towards eea-4,2m

Yopening or slot 45 and form a support for the cutting edge 84 of therazor blade 15 for shaving purposes; so that this comb or guard section18 and the comb or guard section 19, which is adapted to support thecutting edge 81, form the support for the two cutting edges of adouble-edged razor blade 15. Naturally, when the razor blade 15 ispositioned upon the platform 14, the tension of the spring 39 pressingand forcing the platform 14 upwardly will hold such blade 15,frictionally secured, upon its seat between such platform 14 and theroof or cover 28.

Arrow E indicates a razor blade magazine carrying a stack of razorblades 15, supported by a spring 51 which is secured to the floor 52 bysuitable means, for example, rivets or screw elements 53. The front wall54, is provided with an outlet slot 55, having enlarged end openings 56to prevent marring of the cutting edges of the razor blades 15, whilesuch blades are being fed from the magazine into the razor head. 'Thefront wall 54 is provided with aV zig-zagged or corrngatedly shapedelement or fin ger 57 of a style tapered, gradually, downwardly to anarrower size as shown at arrow Ba than that of its upper sectionindicated by arrow Ca, of a size titing slidably into the slot 31.

The inner face 58 of the frontv wall 54 and the inner face 59 of therear wall 6i?, of the magazine arrow E, arc each provided withextensions 61 adapted to fit within the end portions of the slots 62 ofthe blade 15, thereby holding the stack of blades 15 in desired positionwithin the magazine without marrin'g their cutting edges. The upperportions of the side walls 63 and 64 are each provided with a slot 65. Aiiat shaped feeder 66 is positioned within such slots 65 having the endportions thereof bent upwardly and over the top wall 67, as at 68,forming gripping means 69.

When it is desired to feed a razor blade from the maga- Zine into therazor head; the magazine nger 57 should be placed into the finger slot31, the frontportion 71 of the finger 57 will enter the space 72 andslide into position between the members and 11, separating these twomembers from each other, 'for example, in a manner as shown in Fig. 2.The upper end portion 73 of the ringer 57 will, slidably, engage theprojection or shoulder portion 74 of the member 10, and the lowerportion 75 will engage, slidably, the extension 12 thereby moving theinner member 11 downwardly separating the front-portion 76 of theplatform 14 from the front portion 77 of the roof or cap 28, thusproviding space for the blade to enter the seat'space 78. By moving thefeeder 66 towards the outlet slot 55 the uppermost blade 15 will bemoved into desired position within the razor head, for example, asl

shown in Figs. 3 and 15, and when the linger 57 is withdrawn from theslot 31 the inner member 11 will, by pressure of the spring 39, beforced towards the outer member 10, bringing the extensions'79 in directengagement with the end portions of the cutting edge 81, as at 32, andwill also bring the inner faces S3 of the bulged, curve or bent portions26 in direct engagement with the end portions of the cutting edge 84, asat 85, and permit yieldable pressure thereon and also of the platform 14against the blade 15, forcing same upwardly against the roof or capportion 28, thus holding the blade 15 in a locked position for shavingpurposes. The rear end p0rtions of the platform 14 and roof or cap 28are tapered as shown at arrow F to facilitate the opening and closingoperation of the front portions of such members.

It can be seen that turning the knurled head 41 into desired directionthe tension of the spring member 39 will be increased, whereas turningsuch knurled head 41 into opposite direction will reduce the tension ofthe spring member 39, thereby adjusting the pressure ofthe spring member39 against the inner member 11 to desired degree; whereas `thhe completeremoval of the screw element 40 from the screw-threaded opening'37 willseparate the parts of the structure from each other for cleaningpurposes. it will thus be seen thatV the knurled-head screw structureperforms several functions; namely, holding the parts in assembled formfor shaving purposes, adjusting the spring tension to desired degree,and separating the parts for cleaning purposes. The extension 44 beingpositioned within the slot 38 prevents rotatable movements of the springmember 39 thereby holding the bulged p0rtions 42 and 43 in desiredposition. Of course, the disclosures herein are for illustrativepurposes only and not for limitations; for example, if desired thescrew-threaded member 40 may be eliminated and a rivet may be usedinstead in a manner holding the parts permanently together, or variousother changes in form of structure may be resorted to without departingfrom the spirit of this invention.

For clarification purposes the following may be pointed out. While theordinary type of razor blades may be made to be used in connection withmy injector razor, yet, for the purposeof providing means whereby asuperb shave may be obtained, I provide my razor blade 15 with a newkind of cutting edge; I over-grind the longitudinal upper end portion ofthe cutting section and form a convexed shape as shown at 91, and then Iunder-grind the underface of the razor blade as shown at 92, therebyforming an angled keen sharp cutting edge 9.3. It is believed that suchangled cutting edge will afford a more satisfactory shave than may beobtained from the ordinary type of cutting edge. The thickness of theblade in the illustrations has been greatly exaggerated to show clearlythe construction or shape of my new cutting edge.

I desire it to be understood that the disclosures herein are forillustrative purposes only and not for limitation purposes. My injectorrazor, and magazine, may be made of various suitable materials, theparts may be made in any desirable manner, for example, machined,stamped, molded, pressed, extruded, or die-casted, and be made in anysuitable style, size or shape.

From the above it will be evident that my invention, hereinaboveillustrated and described, teaches an entirely new principle in the artof shaving-implement construction. The novel manner, or form, of myinjector razorhead structure, the two comb sections for supporting thetwo cutting edges of a double-edged razor blade, and the roof portionthereover and the adjustability of same with respect to each other, theyieldable engaging means of the head-structure for frictionally engagingthe doubleedged razor blade during its slidable movement while being fedfrom the blade magazine into such head structure, the means for holdingsuch double-edged razor blade in locked position for shaving purposes,the adjustable tensioning means, the simplicity of taking the sectionsapart for cleaning purposes and for reassembling same, the novel slotand key structure, are important and useful features. It will thereforebe seen that the structure herein illustrated and described is of anovel patentable nature, practical, it can be utilized togreat advantageby the user, and is therefore believed to be of commercial Value.

From the above it will be seen that I have invented and perfected ashaving-implement comprising an injector razor of a new and uniquedesign and structure, an injector razor which is practical, useful andtherefore of commercial value, and although I have shown certainpreferred forms or illustrations in order to explain Vand describe thenovelty of my invention, yet, by showing such structure, I do not, byany means, limit myself to these structures, nor to the terms used indescribing same, as they are for illustrative purposes only. Varioussuggestions and changes of structure may be resorted to, and I desire itto be understood that I have same in mind when showing and describingthis invention, and seek protection by Letters Patent. And, although Ihave mentioned in describing this invention of what material certainparts may be made, how they may be formed, shaped or styled and how theymay be assembled, yet I desire it to be understood that this structure,or parts thereof, may be made of any suitable material, and shaped,formed, styled or arranged in any desirable manner, and assembled in anyconvenient way so that the parts may be easily taken apart, removed,cleaned, replaced and reassembled, and that various changes in detailmay be resorted to without departing from the spirit of this invention.
